Before the extruder is stopped, the mold should be turned to have an interval of 5 to 10mm to make the hinge (bending arm) structure of the clamping machine in a semi-straightened state, so that the hinge structure (bending arm) of the extruder will not maintain force, so as to better maintain the mold and clamping structure.
Before stopping the machine, the plastic in the bucket should be cleaned, and the plastic between PP, PS and PE should be used to clean the original plastic remaining in the bucket. After cleaning, loosen the screw to the maximum length of stroke, which can avoid burning the screw head when the power is turned on next time.
(1) If the plastic used is HB general plastic, natural plastic can be cleaned without cleaning the plastic inside the extruder barrel.
(2) If the plastic used is colored, you must use the plastic between PP, PS and PE to clean VO fireproof plastic, corrosive plastic and glass fiber plastic. After the cleaning operation is completed, the temperature of the material pipe can be directly lowered.
Before completing the screw operation of the extruder barrel, please confirm whether the power switch of each injection molding equipment has been turned off, whether the doors and windows have been closed. What's more, the workshop should also take a good method to prevent rat bites. We should make sure that extruder electromechanical control box has been closed to prevent rats from entering the interior and damaging the main engine.
Cold-Forming high-torque shaft with improved strength and fatigue resistance for demanding extrusion conditions.
Best suited for:
High torque extrusion systems
High filler compounding
Continuous high-load production
Barrel with vent openings enabling efficient removal of volatiles under controlled partial fill and pressure conditions.
Best suited for:
Devolatilization
Moisture removal
Vacuum venting sections
Robust rectangular spline design providing stable torque transmission with moderate load capacity.
Best suited for:
Medium torque systems
Chemical processing
Replacement applications
Primary feeding barrel introducing raw materials into the extruder under controlled fill and stable conveying conditions.
Best suited for:
Main material feeding
Pellet and powder input
Stable process start
TME elements use intermeshing toothed discs to split and recombine melt flow, achieving efficient distributive mixing without conveying.
Best suited for:
Melt mixing zones
Fiber-reinforced materials
High homogeneity requirements
SK conveying elements provide approximately 15% higher free volume than standard conveying elements and are particularly suitable for low bulk density materials.
Best suited for:
Feeding zones
Side feeding
Low bulk density materials
